Answer: (-9, -8), (-4, -6), (1, -4)
Let P, Q, R divide AB into four equal parts (A-P-Q-R-B).
Q is the midpoint of AB: \(\left(\dfrac{-14+6}{2},\dfrac{-10-2}{2}\right)=(-4,-6)\).
P is the midpoint of AQ: \(\left(\dfrac{-14-4}{2},\dfrac{-10-6}{2}\right)=(-9,-8)\).
R is the midpoint of QB: \(\left(\dfrac{-4+6}{2},\dfrac{-6-2}{2}\right)=(1,-4)\).
